At 400 V AC it handles motor loads up to 15 kW, with a 50 kA interrupting capacity at that voltage. Ground fault detection is not included; that requires an external module if needed. ## Interrupting Capacity and Coordination SCCR varies with line voltage: 100 kA at 240 V AC, 50 kA at 400 V, 10 kA at 500 V, and 4 kA at 690 V. At 400 V — the most common industrial supply — the 50 kA rating covers most distribution panels without requiring a current-limiting upstream breaker. At 690 V the 4 kA figure is lower; verify the available fault current if running at that voltage. Main circuit terminals are screw-type box terminals accepting 2× (0.75…16 mm²) solid or 2× (0.75…25 mm²) stranded, with a single conductor up to 35 mm² stranded. AWG equivalent: 2× (18…2). Auxiliary and control circuits use separate screw terminals. The terminals accept ferruled stranded wire with core-end processing. Dimensions: 55 mm wide, 140 mm high, 149 mm deep. Zero clearance needed at the sides or rear for mounting. The 55 mm width matches the standard three-pole breaker footprint on DIN rail.","metaTitle":"Siemens 3RV1031-4EB10-0BA0 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1031-4EB10-0BA0 SIRIUS motor-protective circuit breaker, 32 A continuous, CLASS 20 trip, 15 kW at 400 V.
